Anyone know about old schwinn bikes?

Pretty darn nice solid bike. Like I said no expert here, but my uncle had three or four of these in his bike shop in similar condition. He just had them mostly on display. One guy wanted two of them and made him a $1,600 offer my uncle just said I thought you wanted both?

Anyways looks like yours in missing the chain guard and some of these bikes had a disc brake on the rear wheel too along with the drum front. I know the springer front ends should have an "S" on some of the bolts or pins near the top on the sides.

I'm thinking your bike is probably worth somewhere north of $800 to about the $1,200 range, but of course I already stated that I'm not an expert.
